The GIBRALTAR G10-2820-Y is a 4-point lobed knob constructed from phenolic material with a gloss black finish. Designed for hand-tightening and adjusting threaded fasteners, this knob provides a secure, comfortable grip without the need for tools. It features a 1.5-inch head diameter, a 5/16-18 stem thread, and a 1.75-inch thread length, making it well suited for clamping, positioning, and locking applications across a wide range of industrial and mechanical assemblies. Maintenance technicians and mechanical assemblers will find this knob a straightforward replacement or upgrade for standard threaded control points on equipment panels and fixtures.
This lobed knob is appropriate for use in light industrial, commercial, and mechanical service applications where a tool-free adjustment point is required. Typical installations include machine guards, jigs, fixtures, enclosure panels, and equipment adjustment assemblies. The phenolic construction provides adequate rigidity and resistance to moderate heat and chemicals, making it a practical choice for shop and field environments where durability is a priority.
Designed as a standard replacement or upgrade lobed knob for equipment featuring 5/16-18 threaded studs or inserts in industrial, mechanical, and commercial panel assemblies.
Installation is performed by hand threading the knob onto a 5/16-18 stud or threaded insert. Ensure the mating thread is clean and free of debris before installation. No special tools are required for standard hand-tightening applications; however, if a torque requirement exists for the assembly, consult the equipment manufacturer documentation. Inspect the knob periodically for cracking or wear, as phenolic material can become brittle under prolonged exposure to extreme temperatures or harsh chemical environments.
